From his voice he seems like one whose lost hope has been restored by that single win. Gambling can be a life saver too for it's not as bad as non-gamblers portrays it. To all gamblers' when you get lucky make good use of your gambling win do not chase for double portion.
Yes, not only can gambling be a hope restorer, but it has also been a life changer to many who gambled and luckily won a huge sum, because one similarity I have come to notice about all those who won this huge sum while gambling is that non ever knew they will win when they won, but it all came as a surprise, hence, this should be a lesson to all of us to always have an open mind while gambling, so as to accept whatever result that may come our way with an amount we can always afford to lose, so that if we win, we accept it that way, but if we lose, we also accept it with good fate without regret. Rather than gambling all you have with the mindset gambling will someday restore your hope.
You are absolutely correct, that is why they said that gambling is about luck and chance, we can never tell when we will win money, not to bear it in mind that we must win and make profit which can be very harmful to us.
So it's wise for us to gamble with an open heart just like you said and accept whichever way we find ourselves in, if we win or lose, that is our luck for that day or moment which if we try luck next time, we might get what we need or want but let's not take a job like gamble everyday and if we lose its good to stop and try again next time, this way will help us to regulate the way we gamble.
